1.1These test methods describe the use of the Karl Fischer (KF) titration for determination of water in halogenated organic solvents and mixtures thereof. Water concentrations from 2 ppm to 1000 ppm can be determined in these solvents. Two test methods are covered as follows:

1.2Either of these test methods can be used to determine typical water concentrations (15 ppm to 500 ppm) found in halogenated solvents.

1.3These test methods recommend the use of commercially available Karl Fischer titrators and reagents.
